New horizons for glass formation and stability

Nature Materials 14, 542 (2015). doi:10.1038/nmat4292 Author: A. Lindsay Greer It has long been thought impossible for pure metals to form stable glasses. Recent work supports earlier evidence of glass formation in pure metals, shows the potential for devices based on rap ... mehr

Is metallic glass poised to come of age?

Nature Materials 14, 553 (2015). doi:10.1038/nmat4297 There have been a number of attempts to commercialize bulk metallic glass over the past 20 years. William L. Johnson, the Mettler Professor of Materials Science at California Institute of Technology, has been a prominent ... mehr

Tuning order in disorder

Nature Materials 14, 547 (2015). doi:10.1038/nmat4300 Author: Evan Ma Recent research has revealed considerable diversity in the short-range ordering of metallic glass, identifying favoured and unfavoured local atomic configurations coexisting in an inhomogeneous amorphou ... mehr

Morphological and immunohistochemical analyses of soluble proteins in mucous membranes of living mouse intestines by cryotechniques

We have performed immunohistochemical or ultrastructural analyses of living mouse small intestines using Epon blocks prepared by ‘in vivo cryotechnique’ (IVCT). By electron microscopy, intracellular ultrastructures of epithelial cells were well preserved in tissue areas 5–10 μm away from cr ... mehr

In situ SEM observation of the Si negative electrode reaction in an ionic-liquid-based lithium-ion secondary battery

By exploiting characteristics such as negligible vapour pressure and ion-conductive nature of an ionic liquid (IL), we established an in situ scanning electron microscope (SEM) method to observe the electrode reaction in the IL-based Li-ion secondary battery (LIB). When 1-ethyl-3-methylimid ... mehr

One-step nanopatterning of conjugated polymers by electron-beam-assisted electropolymerization

We propose a one-step nanopatterning method where liquid monomers are polymerized directly with an electron beam under an atmospheric pressure. The method allows precise positional control of an electron beam that induces electropolymerization based on an anodic oxidation only in the irradi ... mehr

Development of a monochromator for aberration-corrected scanning transmission electron microscopy

In this article, we report the development of a new 200-kV analytical electron microscope equipped with a monochromator with an integrated double Wien-filter system. It enables us to study the electronic structures of materials in detail using electron energy-loss spectroscopy (EELS) analys ... mehr

Scanning electron microscopy for flow-diverting stent research: technical tips and tricks

Flow-diverting (FD) stents represent a new concept in the treatment of intracranial aneurysms with challenging anatomical dispositions. Having been introduced to clinical practice only in the last 5 years and featuring complex mechanisms of action, they are still under research. Scanning el ... mehr

A Sensory 3D Map of the Odor Description Space Derived from a Comparison of Numeric Odor Profile Databases

Many authors have proposed different schemes of odor classification, which are useful to aid the complex task of describing smells. However, reaching a consensus on a particular classification seems difficult because our psychophysical space of odor description is a continuum and is not clu ... mehr

Fragile X Mental Retardation Protein Regulates Olfactory Sensitivity But Not Odorant Discrimination

Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and is characterized by cognitive impairments and altered sensory function. It is caused by absence of fragile X mental retardation protein (FMRP), an RNA-binding protein essential for normal synaptic pla ... mehr

Multilayer coextrusion of rubber compounds

This research work presents the first continuous multilayer coextrusion system for high viscosity elastomeric materials. Three unvulcanized rubber materials were chosen to validate the system: two butyl rubbers and a polyisoprene. The elastomers were characterized under oscillatory shear an ... mehr

A simplified kinetics model of natural and iron complex catalysed hydrogen peroxide oxidation of starch

Abstract Hydrogen peroxide is well known as one of environmentally benign reagents for the oxidation of starch. The aim of this work was to develop a simplified model for the describing of mass transfer and reaction kinetics phenomena of non‐catalytic and iron complex catalysed starch ox ... mehr

Rheological properties of nanoemulsions stabilized by Polysorbate 80

Abstract In the work we analyze and determine the rheological properties of nanoemulsions based on three types of oil phases: Crodamol GTCC, Crodamol PC and Oleic Acid. The emulsions were stabilized with the use of Polysorbate 80. Geranic acid has been applied as a model active substance ... mehr
